* Next go to Control Panel > Display. Click on the "Desktop" tab then click the "Customize Desktop" button. Click on the "Web" tab. Under "Web Pages" you should see an entry checked called something like "Security info" or similar. If it is there, select that entry and click the "Delete" button. Click OK then Apply and OK.

When the scan is finished, anything that it cannot clean have it delete it. Make a note of the file location of anything that cannot be deleted so you can delete it yourself.
- Save the results from the scan!

@ Pieter > hi My link may not be the cause - but the information supplied is a bit minimal and this particular trojan does reference the redirection to dns404.net. I'm sure there are other avenues to this change - this was one that I knew was fairly recent and documented.

@ Griogair

I'm sure it's stating the obvious - but if you do go to the dns404.net site - do not download/install 'Spy Trooper'.

and if i type in an adress is redirects to 'dns404.net'

and once it said that it was blocked by some spyware application.

This is just another chain of the con & should be avoided at all costs.
